Runtime Environment: All distributed memory tools were run on the Extreme Science and Engineering Discovery Environment (XSEDE) [1]} Comet cluster at the San Diego Supercomputer Center (SDSC). All Comet compute nodes are equipped with 2 sockets \(\times \)  12 cores of Intel Xeon E5-2680v3 processor, 2 NUMA nodes \(\times \)  64GB DRAM, 56 Gbps FDR InfiniBand interconnect and Lustre shared file system. The maximum number of nodes allowed per job is 72 and maximum allowed job time is 48 hours. The shared memory tools, on the other hand, were run on a local server system equipped with an Intel Xeon Gold 6152 processor (22 physical cores, 44 hardware threads), 128GB DRAM and a local 6TB SSD storage as most experiments using the shared memory tools required \(>\) 48 hours (job time limit on XSEDE Comet).
